Review: Milk and cereal in a bar instead of a bowl? It's popular with the elementary-school set. I offered the Cinnamon Toast Crunch cereal bars to the neighbors' four granddaughters, ages 5 to 10, and my own two preschoolers. The bars were devoured in seconds. All the kids loved the sticky-sweet milk filling, similar to sweetened condensed milk. The older girls said they'd definitely welcome these bars as a quick breakfast on a busy morning or as a lunch-bag treat.
